If someone writes a thread that goes viral, and you and they fight on it:

It’s probably a good idea to start a new thread if what you really want is to talk about the issue, but not with them.

And if they start a new thread, it’s usually better to stay off it. Because they probably started the new thread to get away from the argument you were having. And the fact that they want to discuss something doesn’t mean they’re obligated to discuss it with you.
